Benefits of technology
[0024]The principle of operation of the security switch disclosed herein relies solely on manual disconnection (or connection) of audio / video / communication or power supply components in the personal device in order to avoid unauthorized access to the information or personal device. This provides full isolation even in cases of full access to the device software or remote access to electronic components of the device, in the sense that an unauthorized user is not able to connect electrical circuits that are switched off manually, and a beneficiary side effect of power saving in case of power supply disconnection.
[0032]In some embodiments there is provided a method for securing a personal device that includes a device core and a peripheral device from unauthorized access or operation, comprising the steps of providing an internal isolated switch having operating functions that cannot be affected by either the personal device core or the peripheral device, wherein the isolated switch includes an internal component located within the envelope or at least partially on the surface of the personal device, wherein the isolated switch internal component is selected from the group consisting of a mechanical element without an electrically operated bypass and an electronic / electrical element separated electrically from elements or components of the personal device, and wherein the isolated switch is configured to act as man in the middle between the device core and the peripheral device, and using the isolated switch to protect the device from unauthorized use or access.
Problems solved by technology
A remote unauthorized user can adversely use these communication means to try and break open the personal device security and obtain personal and other information on the personal device user or owner, or to perform unauthorized operations on the user's behalf.
A single personal device may have a number of different communication means such as phone-lines, cables, a wireless LAN, Bluetooth, etc, which only increases the security risk.
Components of a device / appliance that are controlled by software and electronic switching devices may be controlled by an unauthorized user even if they were disabled earlier by the authorized user.
Local authorized or unauthorized users can easily modify the software operating the personal device, thereby causing a security breach, e.g. by downloading a virus-affected software update.
This scenario of software modification is very common: on one hand it is much easier than hardware modification, and on the other hand it is much harder to verify such a modification, or notice unwanted change.
However, each new software security system is eventually overcome by new hacking methods, viruses, worms, Trojans and other threats.
This creates an endless competition between security providers and unauthorized users.
In essence, software security is hard to implement and / or prove.
Even if the theoretical model of the security is proven, there may still be a mistake or bug in the implementation that allows a break in the security.
Consequently, software security solutions cannot be trusted.
All existing protection solutions suffer from one of two disadvantages: either the switch is “external” and can therefore be tampered with by an external factor, or the switch is internal but not fully isolated from the device itself (and therefore can be manipulated by the software of the device).
Consequently, existing solutions cannot provide simultaneous temporary protection from audio / video information capture, cannot provide simultaneous temporary protection from both audio / video information capture and unauthorized access and user location\device location and cannot provide secure security mode exit or prevent capture of the logic required for exiting the security mode.
Existing internal switches cannot provide prevention of false notification about the device security mode in a device with already broken software security, i.e. in a state in which an unauthorized user gains access or control of the personal device despite software protection solutions.
This provides full isolation even in cases of full access to the device software or remote access to electronic components of the device, in the sense that an unauthorized user is not able to connect electrical circuits that are switched off manually, and a beneficiary side effect of power saving in case of power supply disconnection.
In mode 2, the communication to the device is completely disconnected, so the device location cannot be discovered by any means and no information transfer is possible.
When an electrical circuit is broken manually, it cannot be reconnected by an unauthorized user even in case of full access to the device software or by remote access to an electronic personal device.
When all components capable of capturing audio / video information—i.e. microphone(s), headphone(s), speaker(s), and camera(s) are disconnected, information cannot be obtained by an unauthorized user.
When all components capable of transmitting a signal from or to a user's device or appliance (i.e. RF, WiFi, Bluetooth, NFC, and LAN) are disconnected, the user location and other private information cannot be obtained by an unauthorized user.

Embodiment Construction
[0052]The invention discloses security systems and devices for protecting personal devices and their users from unauthorized access, operation, identity theft or information theft. In particular, the invention discloses a security switch that provides total protection of information related to the personal device or a user of the device. In the following description, like elements appearing in different figures are numbered identically.
[0053]FIG. 1 shows a first embodiment 50 of a personal device with a security switch disclosed herein. Personal device 50 includes a device core 100, an isolated switch 102 and at least one peripheral device 104. The dotted arrows indicate an optional direct connection between device core 100 and peripheral device 104 and / or between device core 100 and isolated switch 102. Device core 100 operates by software and may include one or more controllers (e.g. central processing units (CPUs)), one or more memory units and one or more power management module...

System and method for securing a personal device that includes a device core and a peripheral device from unauthorized access or operation. The system comprises an isolated switch, included fully or partially within an envelope of the personal device. The isolated switch cannot be affected in its operation by either the device core or the peripheral device. The switch may be operated by an authorized user of the personal device either preemptively or in response to a detected threat. In some embodiments, the isolated switch includes an isolated controller which can send one or more signals to the peripheral device and / or part of peripheral device. In some embodiments, the isolated switch includes an isolated internal component and an isolated external component, both required to work together to trigger the isolated switch operation. In some embodiments, the isolated switch includes an isolated disconnector for connecting and disconnecting the device core from part of the peripheral device.
